Built in June of 1937 by Southern Pacific Foundry Co., this brown 50' gondola with straight sides and drop ends has white stenciling and runs on box car red Bettendorf trucks. The road name 'Southern Pacific Lines' is arranged within concentric circles in white. The AAR Class GB designates it as an open top car having fixed sides, fixed or drop ends and solid bottom, suitable for mill trade, principally coal and stone.
